Coolbank Stuart rear idler wobbly

[ColemanCollector]

While working on my Coolbank Stuart I noticed a huge amount of lateral play in the rear idler, as in 3mm each side off center! As you can see in pics below, the pin used to mount the idler arm is a much smaller diameter than the hole it goes through. Is there supposed to be a bushing of some sort in there?

No big deal to fill with JB Weld and then drill to fit the pin, but it seems pretty sloppy from Coolbank. This was a preorder Stuart from Banggood so early in production, and so far the gun wasn't connected to the servo, masking tape still on the headlights, and the mounting screws on the bogies in backwards. Friday tank...sigh...

Thanks, Mike.

All mine came with masking tape on the headlights

Hello,
masking Tape on the headlight is standard...
I press a piece of brass tube in the idler.
However, a little bit of play is necessary, otherwise the track will run off.

I went the "fill it with jb weld" route, and drilled it the correct diameter for the pin. Perfect correction for a sloppy bit of Coolbank design. I will never carp about a wobbly HL suspension again...
